This is a comprehensive textbook and reference that provides a solid
background in active sensing technology. Beginning with a historical
overview and an introductory section on signal generation, filtering and
modulation, it follows with a section on radiometry (infrared and
microwave) as a background to the active sensing process. The core of
the book is concerned with active sensing, starting with the basics of
time-of-flight sensors (operational principles, components), and goes
through the derivation of the radar range equation, and the detection of
echo signals, both fundamental to the understanding of radar, sonar and
lidar imaging. Several chapters cover signal propagation of both
electromagnetic and acoustic energy, target characteristics, stealth and
clutter. The remainder of the book involves the basics of the range
measurement process, active imaging with an emphasis on noise and linear
frequency modulation techniques, Doppler processing, and target
tracking.

Key Features

Extensive use of worked examples based
on sensors that the author has developed or worked on during the
past 28 years

Examples are featured that illustrate
the process of designing a sensor for a particular application,
ranging from such diverse topics as the design of a ship-borne fire
control radar to a UAV based lidar scanner to detect locust swarms

For a broader appeal, complicated
mathematical derivations are avoided unless absolutely necessary,
and electronic details of the sensors are limited to block diagram
and algorithm level

There are 572 figures of which about 20%
are photographs, the remainder drawings with 25 tables

About the Author

Graham Brooker has nearly thirty years in radar research and
development. His work includes a broad range of subjects from systems
engineering and developing RF components to writing software for radar
and EW applications; developing new millimetre wave radar sensors for
mining applications. His MSC was completed in 1983; he later completed
his PhD. Before emigrating to Australia, he ran a laboratory that
developed millimetre wave radar systems for both defense and commercial
clients. Dr. Brooker has spent the last eight years developing and
lecturing the Sensors and Signals course at the Australian Centre for
Field Robotics in the University of Sydney. Also, he has presented more
than 40 conference papers, various book chapters,as well as writing more
than half a dozen journal papers.
